Enable MPLS

Following we explain the parameters to modify so that the routers support MPLS within the mini-Internet.

Turn on LDP on the FRR routers

You must turn on the LDP daemon in the FRR routers by replacing ldpd=no with ldpd=yes in the daemons configuration file. By default, the option is disabled.

Give full privilege to the containers running a router

To enable MPLS on the interfaces of the routers, the containers hosting the routers must start with the --privileged option. You need to update the setup/container_setup.sh script to do that.

[!WARNING] Whenever possible you should avoid using --privileged and give access to the router containers using bash (with the linux option in the l3_routers.txt configuration file) to prevent security issues.
